GAS TIP OR NOZZLE.

SPECIFICATION forming part of Letters Patent No. 576,259, dated February2, 1897.

Application filed July 10, 1895- $erial No. 555,591. (No model.)

To '(tZZ whom it may concern: I

Be it known that I, JAMES II. DIAMOND, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in GasTips or Nozzles 5 and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which- Figure 1 indicates an elevation of myimproved gas-regulating tip or nozzle. Fig. 2 is a vertical section ofthe same. Fig. 3 is a plan view of the same. Fig. dis an elevation Fig.5 is a vertical section showing thimble adjusted to open the side portsat the base of the nipple. Fig. 6 is a plan, the adjustable thimblebeing removed.

My invention relates to tips or nozzles for gas-burners; and it consistsof the novel construction and arrangement of parts hereinafterdescribed, reference being had to the accompanying drawings, formingpart hereof.

Referring to said drawings, 1 is a gas nozzle or tip adapted to beconnected with a gas supply, (not shown,) the lower portion of the samebeing externally screw=threaded to admit of this. The upper portion ofsaid nozzle or tip is considerably smaller in cross-section than thelower portion and terminates in a conical-shaped point. Said nozzle ishollow and provided with a small opening 2 in the extreme point thereof,also upwardly-inclined openings 3 3 formed in said nozzle a slightdistance below the cone-shaped point thereof. Said openings 3 3 areadapted to be controlled, that is, opened and closed, by an adj u'stablethimble 4:, which is internally screwthreaded and adapted to move freelyon the upper portion of said nozzle, the lower end of said thimble beingprovided with a flange 5,

the outer periphery of which is serrated to enable the same to bereadily screwed and unscrewed on said nozzle. 'In the upper end of saidthimble is formed an opening 6, in which the cone-shaped point of thenozzle projects.

It will be observed that the openings 3 3 are opened and closed by themovement of the thimble upon the upper portion of the nozzle, so that inthe event of a low pressure of gas a larger quantity of gas may beadmitted through said openings 3 3, and thence through the opening 6,whereby the gas admitted through the opening 2 in the end of the nozzlemay be augmented or increased.

In the event of higher pressure the openings 3 3 may be closed entirelyby screwing or tightening the thimble upon the nozzle until thecone-shaped point of the nozzle is brought into contact with thecorrespondingly-beveled sides of the opening in the top of the thimble.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s-

In a gas-nozzle substantially as described,

the combination of a nozzle the lower end of which is larger incross-section than the upper, and externally screw-threaded, to admit ofits being connected with a gas-supply pipe; the upper end of said nozzleterminating in a cone-shaped point, having an orifice therein andprovided witha number of inclined openings in the sides thereof near thebase of said cone-shaped point; and a thimble freely mov able upon theupper end of said nozzle, and having an opening in the top thereof, the

sides of which are correspondingly beveled with the cone-shaped point ofsaid nozzle, sub stantially as described.

In testimony that I claim the foregoing I hereunto affix my signaturethis 13th day of May, A. D. 1895.

JAMES H. DIAMOND.
